Abstract

The invention provides an Automatic NC inspection and centering method used for determining centering accuracy of an edge detector. The NC automatic inspection and centering method comprises the following steps: (1) determining centering manner of a workpiece, and extracting a straight line on the reference edge of the workpiece; (2) adding a new program, selecting a PLANAR_MILL processing method, selecting the extracted straight line on the boundary of the workpiece, setting relevant parameters, and generating the program; (3) checking the program, and sending a processing program list to the NC for processing after checking correct. Compared with the prior art, the automatic NC inspection and centering method can be operated without repeated check to determine the correctness of centering operation, and can complete the operation in only 20 seconds with an accuracy up to 0.01mm, thereby improving efficiency and accuracy of centering operation, and obviating origin location mistake caused by negligence of an operator.

Description

NC self-verifying divides middle method

[technical field]

The present invention relates to minute middle work on a kind of workpiece, be specifically related to a kind of NC of utilization program and come self-verifying to divide the accuracy of middle work.

[background technology]

Mould parts is in process, after clamping, can do calibration ajust, minute in determine the work such as workpiece initial point, wherein, in minute, determine that this action of workpiece initial point is the basis of carrying out a part, this work has certain technology content, needs staff very conscientiously to do and will do repeatedly to check and guarantee errorless just can process afterwards.

In prior art, generally in process, with seeking limit device, determine the initial point of workpiece in coming minute, but have following shortcoming simultaneously:

(1) use and to seek limit device inspection, rely on processing staff's technology to do completely, inevitably there will be miscount, forget partially the carelessness such as number, the skew that has caused initial point to set, thus workpiece is scrapped and has been affected processing cost and working (machining) efficiency;

(2) use and to seek in the process of limit device, NC personnel will ceaselessly observe the friction situation of limit device and workpiece of seeking, the data of lathe display screen, calculate minute middle data, and NC personnel's efficiency is not high and easily occur mistake;

(3) pottery that is mostly using is now sought limit device, and its price is higher, due to the mistake in using that operating personnel cause because of carelessness, easily causes fractureing of minute middle rod, causes certain loss.

In view of this, be necessary in fact to provide a kind of method improve minute in efficiency and the accuracy rate of work, avoid because grasping the mistake of the original point position that machine personnel's carelessness causes.

[summary of the invention]

In order to achieve the above object, the invention provides a kind of NC self-verifying and divide middle method to detect to seek Qi Fenzhong place of working, limit accuracy, NC self-verifying of the present invention divides middle method to comprise the following steps:

(1) determine minute middle mode of workpiece, at the reference edge extraction straight line of workpiece;

(2) a newly-increased program, selects PLANAR_MILL job operation, chooses the straight line of above-mentioned extraction on the border of workpiece, sets relevant parameter, generator program;

(3) scrutiny program, checks that going out job sequence list after errorless send NC processing.

Preferably, the be appointed as-0.3mm of processing bottom surface of workpiece in described step (2).

NC self-verifying of the present invention divides middle method, determined workpiece minute in after, the article one of dividing Program to be made in each workpiece job sequence list self-verifying, NC personnel observe the cutting situation of cutter in this program process, determine workpiece minute in whether accurate.

Compared to prior art, NC self-verifying of the present invention divides middle method without repeatedly checking errorless could processing in definite minute, inspection of the present invention divides the operating process of middle method only to need 20 seconds, accuracy is within 0.01mm, place of working efficiency and accuracy rate in having improved minute, avoided the original point position mistake causing because of behaviour's machine personnel carelessness.

Fig. 2 illustrates the schematic diagram that divides middle mode for workpiece in the embodiment of the present invention.

Fig. 3 illustrates the schematic diagram into workpiece cutter track in the embodiment of the present invention.

[embodiment]

For object of the present invention, function and technological means are had to further understanding, now the present invention is described in detail.

The invention provides a kind of NC self-verifying and divide middle method, it comprises the following steps:

Step 101: determine minute middle mode of workpiece, as shown in Figure 2, processing mode during this workpiece 10 adopts and divides on four sides extracts respectively four straight lines 20 on the reference edge of workpiece;

Step 102: a newly-increased program, select PLANAR_MILL job operation, on the border of workpiece 10, choose respectively four straight lines 20 of above-mentioned extraction, processing be appointed as-0.3mm of bottom surface, set relevant parameter, generator program, processes workpiece 10 according to the border of setting, as shown in Figure 3, program control cutter is processed along NC cutter track 21;

Step 103: scrutiny program, checks that going out job sequence list after errorless send NC processing, the accuracy in finally determining minute.

NC self-verifying of the present invention divide the formula of middle method can be made in each workpiece job sequence list one, NC personnel observe the cutting situation of cutter in this formula process, if cutting is normal, can carry out ensuing processing; If there is over-cutting, just need to reaffirm the reset of workpiece.

Compared to prior art, NC self-verifying of the present invention divides middle method without repeatedly checking errorless could processing in definite minute, inspection of the present invention divides the operating process of middle method only to need 20 seconds, accuracy is within 0.01mm, place of working efficiency and accuracy rate in having improved minute, avoided the original point position mistake causing because of behaviour's machine personnel carelessness.

Be pointed out that, the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, all fall within the scope of protection of the present invention.

Claims (2)

1. NC self-verifying divides a middle method, it is characterized in that, it comprises the following steps:

(1) determine minute middle mode of workpiece, at the reference edge extraction straight line of workpiece;

(2) a newly-increased program, selects PLANAR_MILL job operation, chooses the straight line of above-mentioned extraction on the border of workpiece, sets relevant parameter, generator program;

(3) scrutiny program, checks that going out job sequence list after errorless send NC processing.
